The ATS A40/A50 TCM Relocation Kit is the ultimate solution for the common issue of Transmission Control Module (TCM) failure in GM Duramax trucks from 2006 to 2015. The factory TCM, particularly the A40 and A50 models, is mounted near the radiator, where it is exposed to excessive heat. This can cause the internal components of the TCM to melt, leading to costly repairs and vehicle downtime.

The ATS Relocation Kit addresses this issue by moving the TCM away from the heat source. The kit includes a secure relocation bracket, an extension harness that provides the necessary length to move the TCM without affecting functionality, and all the hardware required for an easy and secure installation. By relocating the TCM, this kit ensures reliable operation and protects your vehicle from unnecessary failures.

The kit is available for different Duramax models:

  • PN# 601-930-4308 for 2006-Early 2007 models
  • PN# 601-930-4326 for 2007.5-2014 models
  • PN# 601-930-4416 for 2015 models

Don’t risk being stranded due to TCM failure—install the ATS TCM Relocation Kit and protect your transmission from heat damage. For a complete TCM upgrade, ATS also offers the T87 TCM Upgrade (PN# 601-940-4368), which improves gas mileage and drivability by better controlling converter lock-up.
